隔离病房回风高效过滤器滤菌效率的实验研究

Experiment on germ filtering efficiency of high efficiency filters on return air inlet in isolation wards

介绍了国外各类高效过滤器的滤菌效率。在安装有高效过滤器的隔离病房回风口进行了发菌实验,计算了B类和C类回风高效过滤器的滤菌效率,证明了当隔离病房回风口安装高效过滤器时,可使用部分循环风。

Presents the germ filtering efficiency of high efficiency filters abroad. Through giving off the germ in front of the return air inlet with a high efficiency filter in an isolation ward, calculates the germ filtering efficiency of B and C type filters respectively. Proves that when return air inlets fitted with high efficiency filters, the circulation air can be partly used in isolation wards.
